Research on the Anonymity Method Based-on k-anonymity for Electronic Commerce

摘要

According to the model of K-anonymity, the attributes of information tables in Electronic Commerce have been divided into three parts: identifier, Quasi Identifier, sensitive information. To conceal privacy information for consumer, the paper adopted a recode method to protect the name and cell-phone number against revealing, used the generalization algorithm to conceal the quasi identifier for consumer. The data resource of paper derived from the Adult database. It has been analyzed on the correlations among of the generalization hierarchy, the ratio of information loss and K. The result provided an alternative scheme of data processing decision for data holder.
